Q. My scottish terrier appears to be having issues with her back right leg lifting it when walking no sign of injury did not want to go out aged 7

Answered By

A. There could be different causes for the signs you are describing.

Patella ( rotula) bone luxation is one of the most common especially if the lameness is intermittent. Stifle (knee) injury especially cruciate ligament damage is another common cause ( the lameness in this cause would be more consistent).

Nerve root compression in the lower back ( in this case the lameness would be called nerve root signature) is possible as well.

There are other options such as hip or different back leg joints problems; I would recommend anyway to have her checked by your veterinarian. A physical examination can easily localise the problem and give you more specific answers.
